installer-package.ps1

# 格式转换工具 安装程序构建脚本
# 流程：先复用 portable-package.ps1 生成免安装版，再用 Inno Setup 压成单文件安装包
# 输出：release\FormatConverter-setup-<版本>.exe（中文向导、可选安装目录、开始菜单/桌面快捷方式、可卸载）
# 依赖：Inno Setup 6 缺失时自动下载并静默安装到 %LOCALAPPDATA%\Programs\Inno Setup 6
# 注意: 本文件必须保持 UTF-8 带 BOM 编码（PS 5.1 会把无 BOM 的 UTF-8 当 ANSI 解析，中文注释变乱码）
